POET Emission Inventory

Global emissions of gases (ozone precursors) from anthropogenic, natural, and
biomass burning sources have been estimated for the period 1990-2000.
Anthropogenic emissions (containing 15 sectors) are based on national activity
data (fuelwood combustion per year), emission factors (kg CO/ kg fuelwood
combusted par activity), and grid maps (e.g. population maps) for spatial
distribution of the emissions within a country. Biomass burning emissions are
estimated with a climatology from Hao et al. (1994), and ATSR active fire maps
are used for the spatial and temporal distribution of the emissions. Biogenic
emissions are estimated with a vegetation canopy model.
